 Problem description: Drying oil (DO) is produced by thermally decomposing acetylated

Problem description: Drying oil (DO) is produced by thermally decomposing acetylated castor oil (ACO) according to the following reaction: ACO(1) 340 C heur >DO(1)+CH COOH(g) Below is a simple process description: ACO is fed from storage (off site) to vessel, V-101 on the second floor at approximately 3 m height and operating at atmospheric pressure. From V-101, ACO liquid at 30 C is fed to a feed pump (P-101 A/B) at a rate of 0.1 m/min where it is pressurized to 2 barg. The flow of ACO is controlled by a flow control valve situated on the discharge side of the pump. The ACO is fed to a reactor feed furnace (H-101) where the temperature is increased to 340 C, and the stream leaving the furnace is sent directly to a reactor (R- 101) containing an inert ceramic packing, where the decomposition reaction takes place. The single-pass conversion of ACO to Do in the reactor is 40%. The stream leaving the reactor is then fed to flash drum (V-102) where the acetic acid flashes off and leaves in the overhead vapor stream as a byproduct. The DO and ACO liquids have very low vapor pressures and consequently do not vaporize appreciably and leave the vessel as hot liquid product at 310 C. This liquid product is to be cooled down to 160 "C in a separate heat exchanger (E-101). 1- Draw the input-output diagram for the process described above (1 point). 2. For the process described above, use the ASME standards to draw the PFD (using VISIO software) showing the following details (4 points): a- Stream numbers b. Equipment numbers and description c. Information flags d- Basic control loops e. All utility streams 3- Using Heuristic tables for pumps, estimate the efficiency and the power (in kW) for: P-101? (2 points) 4. Using Heuristic tables, estimate the volume and orientation of V-101 (2 points). 5. Is it possible to replace H-101 by a steam-heated shell and tube heat exchanger? Why? (2 points) 6- If the heat flow (mxCpAT) of the process stream used by E-101 is 1.758 MW and a lps is to be produced from this heat exchanger, then estimate the flow rate of this lps in (kg/s) and draw the temperature profiles along the heat exchanger? Assume water is available at 30 C and at a pressure as that of the expected saturated lps steam. Use kettle type vaporizer with water in the shell side (4 points). Note: For part 6 estimate the Enthalpy of vaporization using steam tables and take Cp = 4.21 kJ/kg/K for liquid water. The average density of the process liquid can be assumed 900 kg/m
